| Lesson | Question/Topic | Activities | Case Study/Resources | Assessment | Skills/ICT etc. |
| 1 | Intro to Hydrological Cycle | Global
Hydrological Cycle: movement of water on a global scale: 3 states of water System: Inputs – Process – Output: analogy of computer system: concept of a closed system needs to be understood Evapotranspiration, Condensation, Precipitation, Evaporation, Transpiration |
Water Cycle
diagram for Global / Drainage Basin scale 3 states Pyramid diagram OHTs |
Filling in gaps in water cycle diagram | Glossary: Key Words |
| 2 | Drainage Basin 1 | Drainage Basin
Hydrological Cycle Continue with processes / stores: Surface runoff – go through various types |
OHT sheets Note taking |
Word matching exercise – Glossary test | Numeracy: Water balance work |
| 3 | Drainage Basin 2 | Drainage Basin:
conclusion Go through Sub-surface processes: Soil Moisture, groundwater flow, Infiltration, Percolation Recognition that some of these processes change over time: consider seasonal variation in water table etc. |
OHT sheets Note taking |
Word matching
exercise – Glossary test Plotting of factors over time |
Numeracy |
| 4 | Precipitation | Focus on Rainfall:
formation etc. Need to know principles of cloud formation. Trigger mechanisms. Bergeron Findeisen briefly mentioned. |
Video Need notes on orographic, frontal and convectional rainfall OHTs |
Mapwork: plotting rainfall graphs | Graphicacy |
| 5 | Water Cycle: Measuring aspects of the cycle | Measuring other
aspects of cycle Use of instrumentation: recognizing the problems in observing and recording the weather accurately. |
Instrumentation to measure other aspects of cycle: illustrated sheet of instruments: go through how they work: evaporation pan, Campbell Stokes etc. | Problems of measuring accurately: exercise on reading figures and recording accurately | Numeracy |
| 6 | River Regimes | River Regimes:
annual pattern of river flow – Simple and complex One should be local river, and one on different scale from another part of the world. Sheet of regime graphs. What factors affect the shape of the regime. |
Atlas work:
identifying climate and how it may affect rivers in those areas. CS: 2 rivers with contrasting regimes Plot regime over Water year using data Sheet of regime details. |
ICT: use of
National Water Archive Identify local rivers: Mapwork |
ICT |
| 7 | Hydrographs 1 | Hydrograph:
labeling – contrast storm hydrograph with regime Remember that hydrographs don’t necessarily have to be storm hydrographs. Consider annual hydrographs. Rising and recessional limb, lag time, peak discharge, baseflow cutoff |
Labeling of storm hydrograph | Plot storm and annual hydrograph – relate to incidents – exercise similar to that in Geog.1 | Numeracy |
| 8 | Hydrographs 2 | What factors
affect the shape of the hydrograph ? Physical Factors: weather, climate, rock type, soil, relief, vegetation, antecedent conditions Human Factors: urbanisation, drainage and land uses |
Note taking OHTs |
Comparing 2 hydrographs: Wye and Severn | |
| 9 & 10 | Flooding 1 | Flooding: Identify
1 flood event. Quickly go through the main Physical and Human causes of flooding Show Lynmouth Video Can use other Flood events: need to do some research on the causes and effects of the event. |
Will be using a
named example. Offer a couple of alternatives e.g Lynmouth Flood, 1952 Look at work of Environment Agency |
PowerPoint work Internet Research |
ICT |
| 11 | Flooding 2 | Identify the
physical and human causes of the flooding Add these to PowerPoint presentation. |
Identify causes of
flooding Note taking. |
Internet Research based on geographypages | ICT |
| 12 | Flooding 3 | Finish putting together Power Point presentation on flooding | Put together
slides on causes, effects of flood Continue to develop chosen example of flooding. |
Use of ICT: sites from geographypages | ICT |
| 13 | Downstream changes | River changes
downstream Graded Long Profile Processes: Erosion – Transport – Deposition Compare expected and observed changes Chance of extending this with ICT exercise following a river downstream. |
Plotting long
profile Considering change in a river over time. ICT: photo interpretation. Mapwork – identifying locations, possibly plotting valley cross profiles at different stages of the river’s course. |
Graphing. Mapwork. ICT |
Graphicacy |
| 14 | River Processes | Need to know
processes of erosion: abrasion, attrition, corrosion and cavitation. Need to know processes of transportation: suspension, solution, saltation and traction |
OHTs | Past Questions. | |
| 15 | River Landforms 1 | Landforms of
Erosion Need exemplified and located landforms. Students to make their own notes on these – could do a photo interpretation exercise, or mapping exercise. |
Valleys, Waterfalls, Rapids, Meanders | Note taking OHTs Need annotated diagrams |
Note taking continued. |
| 16 | River Landforms 2 | Landforms of
Deposition Where and why does deposition occur ? Recognise that this is the final stage in a sequence of processes. Need exemplified and located landforms. |
Braid Bars, Levees, Ox Bow Lakes, Deltas, Flood Plains | Note taking OHTs Need annotated diagrams |
Note taking continued. |
| 17 | Case Studies | Go through named
and located case studies of the features mentioned in the previous 2 lessons Depending on size of group, possibility of field visit to River Nar |
Possible fieldwork visit to River Nar. | Past Question. | |
| 18 | Hjulstrom Curve | Go through the
diagram, and explain how it works. Need to be able to see how river velocity
affects the various processes. Also relate to Manning’s ‘n’ and other factors. Be familiar with fall velocity line and erosion velocity band. |
OHT of Hjulstrom
curve Past Question |
Past Question. | Exercise using Hjulstrom curve to interpret data. |
| 19 | River Management 1 | Management of
river processes Attempts to control flow of Mississippi or Colorado or Conwy (MJD) Emphasis on the management of processes rather than flooding causes or water supply. |
Video | Synoptic | |
| 20 | River Management 2 | River in LEDC:
Brahmaputra/Ganges scheme At least 2 examples need to be studied. Could also consider the Aswan High Dam on the River Nile. Emphasis on management in the wider context. International dimension needs to be considered in these examples. |
Video Web research Geography Review Article |
Synoptic | |
| 21 | Groundwater | Problems in
Bangladesh with Iodine contaminating groundwater. The nature of groundwater. Consider the London aquifer - look at the nature of groundwater provided for London – also use by Anglian Water. |
Comprehension
exercise with articles and questions. ICT: Web research |
